Description
Technical field
The present invention relates to the hybrid-power battery field, a kind of specifically explosion-proof electrokinetic cell and manufacturing approach thereof that adopts the injection moulding process fixed electrode.
Background technology
Hybrid-power battery has very far-reaching prospect as novel energy on using.But also exist in its production and the use some problems just take capacity bigger electrokinetic cell for example, some models that have now are such as 40Ah, 50Ah, these products commonly used of 60Ah.The extremely conflict of contradiction is arranged in product design; Owing to be large-capacity multipurpose on electric automobile, electric bicycle and products such as electric tool that some are large-scale; Voltage is about 500V-600V (automobile batteries) generally, so will inevitably pay the utmost attention to the fail safe and the stability of battery.
As everyone knows, battery itself is exactly a power supply independently, has positive pole and negative pole; The charging and discharging currents of the battery that capacity is little itself is also just relatively little, and the hybrid-power battery discharging current is generally all more than 20C, so from security consideration; Most of producers are most non-metal shells that adopt in the design motivation battery, and reason is exactly the defective that as far as possible reduces battery itself, most importantly Insulation Problems; When electrokinetic cell uses, can not use simple lead-out wire as connected mode because above mention the discharging current problem, must use metal electrode to draw form; Great majority all are with the fastening method connection electrode of screw, so must use non-metal shell.So just certainly existing the conflict in the design; Conclude be divided into following some: 1., heat dissipation problem; Hybrid-power battery just can produce certain heat in use when carrying out heavy-current discharge, the equipment of adding general use hybrid-power battery is such as automobile; Be not simple one group or several groups but tens groups hundreds of group even, this is that the heat that produces is well imagined.The battery of non-metal shell is easy to produce phenomenons such as casing deformation, short circuit under this operational environment, be easy to cause fire (shell itself is exactly inflammable thing) when serious.Environment for use can have influence on the heat dissipation problem of battery equally; Hybrid-power battery is very wide as the new forms of energy applicable surface; Have a lot of environmental factors when using battery; Such as in airtight, high temperature, condition such as freezing, so just will be very strict to the requirement of battery self " quality ", and non-metal shell to the adaptability of adverse circumstances just seem relatively weak tendency some.2., vibration resistance problem; Owing to be to draw as electrode,, will inevitably produce vibration in motion such as automobile so on applicable elements, just have certain constraint with the screw form; Be to produce to become flexible with the screw form as connected mode like this, can produce adverse consequences when serious.
Summary of the invention
The objective of the invention is to provide a kind of employing metal shell, simple and reasonable, strong to the adaptability of adverse circumstances, the vibration resistance ability is strong, the explosion-proof electrokinetic cell of long service life, employing injection moulding process fixed electrode that fail safe is good.
The objective of the invention is to realize like this; This explosion-proof electrokinetic cell comprises shell, bottom, battery cell, heating panel, loam cake, electrode derivation mechanism; Be provided with heating panel between said two adjacent battery cells; The battery main body that a plurality of battery cells and heating panel fit together formation is set up in the enclosure, and bottom is arranged on the bottom of shell, the electrode derivation mechanism that connects battery main body be set at shell above.
One side of described shell has explosion-proof interface.
Described electrode derivation mechanism comprises that hot melt is fixed on the fixing piece down and the fixing piece of going up of loam cake both sides, is set with insulating case, is plugged in fixing piece down, loam cake and the fixing fairlead of going up on the piece, goes up electrode leads to client that the piece hot melt is fixed together with fixing piece down, loam cake and fixing.
A kind of manufacturing approach that adopts the explosion-proof electrokinetic cell of injection moulding process fixed electrode, this method may further comprise the steps:
1., bottom being installed in a side, to have the end of shell of explosion-proof interface for use;
2., fit together the formation battery main body to a plurality of battery cells and heating panel;
3., electrode leads to client is sleeved in the poor insulating case of bayonet socket shape pin; Electrode leads to client that will have insulating case then is plugged in fixing piece down, loam cake and the fixing fairlead of going up on the piece; To fix down piece through the high temperature fuse machine and fuse the electrode derivation mechanism of the formula that becomes one fully with fixing upward piece and loam cake;
4., battery lead on the 2. middle battery main body of step and the 3. middle sub-link of electrode leads to client of step are linked together through cold riveting, ultrasonic bond or Laser Welding form;
5., the battery main body that will have an electrode derivation mechanism places in the enclosure, simultaneously loam cake is contained in the shell upper end, accomplishes whole manufacturing process.
Advantage of the present invention and good effect:
1, the present invention courageously adopts metal shell, has improved the heat-sinking capability of battery like this, has strengthened the non-deformability of battery, adapts to various hot and cold environments for use, has prolonged the useful life of battery simultaneously.
2, the present invention is because adopt metal shell, so the collision problem of being mentioned above must overcoming.So in design, adopt the electrode Shooting Technique; Electrode carries out the elevated temperature heat blow by the fire resistant resin material and fixes on and cover; Has a good insulation performance property because the fire resistant resin material hardness is high, dimensional stability is good, resistivity is high; Have the scratch-resistant ability, high temperature resistant in addition strong with ability low temperature.So electrode draw thus fixingly can not become flexible, phenomenon such as distortion, will never come in contact with metal shell, cause short circuit.
3, electrode lead-out part of the present invention divides employing two kinds of forms, and a kind of is that copper strips is directly drawn, and another kind is that a screw form is drawn, and can be suitable for various instructions for uses like this.
4, the present invention adopts battery lead and electrode to draw directly to be connected with cold riveting form, ultrasonic bond or Laser Welding, to have significantly reduced connection number of times (for once connecting), improved the stability of battery relatively, reduce the generation of internal resistance, improved productivity.
5, because the raw material sources majority of non-metal shell depends on oil, so be not environment-friendly products, it is not optimal selection that this state is produced the new forms of energy product down.So adopting metal shell to seem than the use non-metal shell pays attention to and environmental protection more.
